"I printed the same 50 pages of plain text and images (600x600 no toner save) as I did on the ML-1210. The entire document took approximately 5 minutes 15 seconds when connected with the USB cable. This comes to a bit under 10 pages per minute as opposed to 11 for the ML-1250. This is where we see the smaller memory size come into play. It's not that much a decrease in speed, but it is somewhat noticeable. If you are considering purchasing this printer then you would most likely want to look into upgrading your memory from 4MB. "
